Procedure
The 4-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-2-azetidin-3-yl-3-ethoxy-6-methylbenzonitrile (0.055 g, 0.14 mmol, chiral intermediate from Example 320, Step 1) was combined with tetrahydrofuran (22 mL), DIPEA (0.049 mL, 0.28 mmol) and oxirane, 2,2-dimethyl-(0.018 mL, 0.21 mmol) at room temperature. The reaction was heated to 95° C. and allowed to stir overnight. The reaction was allowed to cool to room temperature and was purified without workup by prep HPLC on a C-18 column eluting water:acetonitrile gradient buffered pH 10 to give the title compound as a white amorphous solid (0.035 g, 50%). The product was isolated as a single enantiomer. LCMS calculated for C25H34N7O2(M+H)+: m/z=464.3; found: 464.3. 1H NMR (300 MHz, DMSO-d6) δ 8.09 (s, 1H), 7.23 (s, 1H), 6.21 (q, J=6.8 Hz, 1H), 4.00 (m, 4H), 3.81-3.54 (m, 2H), 3.15 (m, 2H), 2.53 (s, 3H), 2.33 (s, 3H), 2.27 (bs, 2H), 1.70 (d, J=7.1 Hz, 3H), 1.30 (t, J=6.9 Hz, 3H), 1.04 (s, 6H).
